Title: Improvements in blade mounting for rotary wing aircraft
IPC: B64C27/51
Filed: 1947-08-08
Abstract: 643,875. Helicopters. AUTOGIRO CO. OF AMERICA. Aug. 8, 1947, No. 21887. Convention date, Sept. 24, 1941. [Class 4] In a sustaining rotor for a helicopter the articulation connecting each blade to the hub comprises a pure drag pivot provided with frictional or like restraint effective to prevent oscillation on the drag pivot in flight, but capable of yielding to allow the mean lagging angle of the blade to alter in response to changes of the torque applied to the hub, and an inclined drag pivot on which the blade is free to move, substantially without mechanical damping, through a limited angle sufficient to accommodate lead-lag oscillations in flight, the inclination of the last named pivot being such that lead-lag movement is accompanied by and compounded with a proportionate flapping movement. The blade 7 is connected to the hub 4 by an arm 9, forked at 10 to embrace one end of a link 12 pivoted thereto at 13 on an axis substantially parallel to the rotor axis. The other end of the link 12 is pivoted at 15, on an axis obliquely inclined to the rotor axis, to the forked end 14 of the blade root 8. One fork of the end 14 is extended to carry a spring-loaded plunger 19 which engages in an arcuate slot formed in the link 12 to limit the relative movement of the blade 7. Stops 20 are provided on the forks 10 to limit relative movement of the link 12, such movement being damped by an adjustable friction damping device 23. The plunger 19 and the stops 20 may be withdrawn to allow the blade to be folded about the pivots 15 or 13. During autorotation the blade 8 will be substantially radial to the hub 4 and normal flight conditions will produce drag movement variations shown by the lines f-f, whilst when the rotor is power driven the blade axis will lag behind the radial position and will experience drag movement variations under normal flight conditions as shown by the lines p-p. These normal variations will occur about the pivot 15, which by virtue of its inclined axis, will produce complementary flapping movements tending to damp the drag movements. When the rotor changes from auto-rotation to powered drive or when changes in rotor torque occur, the frictional resistance of the device 23 will be overcome and the link 12 will move relative to the arm 9 about the pivot 13, thus ensuring that the blade 7 will only oscillate within the limits set by the plunger 19 moving within the arcuate slot in the arm 12. Normal movement of the link 12 is intended to lie within the limits set by the stop 20. Specifications 444,485 and 492,816 are referred to.
